Need help with 70’s johnson motor.

At first it would not do anything when turning the key. Battery is fully charged by AutoZone and tested. Replaced battery solenoid and ignition switch. After putting everything back together, we got power to accessories and gauges. Cranked the engine over and turned over for a couple seconds then nothing again……

Model # of motor ?----Checked the fuse ?

Not sure the model # of motor. I did find out it’s a 1976. Only fuse I know of is a 50 amp fuse coming off the positive side of the battery that looks good.

Check the 20 amp fuse in the wire harness.------Check ground wire from solenoid to the block.

20 amp fuse is blown. Didn’t know it had one there it was hidden. Will replace today and get back, thank you!

Replaced 20 amp fuse and blew instantly. Same thing happened. Turned over for a second and now nothing…..ground wire from solenoid looks fine.

Could a missing battery cut off switch be causing it?

Find a bare / pinched wire somewhere.

Find a bare / pinched wire somewhere.

Found what it was. Took apart the ignition switch again and black ground was slightly touching red 12v starter. Boat started right up after. Thanks!
